alt Hacker NewsI'd argue it's a 4A violation to require it to be displayed, though. It's a search of your registration 'papers' without RAS or PC of an offense.
The fact that driving is a 'privilege' doesn't negate your rights to be secure in your papers, the police should have to have articulable suspicion that your car is unregistered or unlicensed before they can demand you to display your plate.
I dont personally agree but that is a really interesting argument I can kinda get behind. I guess the question is, what if you have footage of a crime being committed, and you would have a great lead if you only had a way to pair a vehicle with a person?
